SIP registration timeout due to stale entry in pfsense state table
-
Have the same issue.
Tried to restart of SIP PBX (asterisk) to check, is it possible to solve it from PBX side. It is not helped.
Reliable automated solution is needed. -
Do you have asterisk set up to do 'qualify=yes' on the trunk? I believe that refreshes the SIP registration…

Interesting idea. I don't think you need to edit the config.xml to set cron jobs though, since a package is available, no?

i have the same issue, but, with not translate.
my voip server = 10.0.0.9
my voip-trunk-server = 201.86.87.5 (vono)everything works fine for a while, then , then it's going sip registry timeout, forever.

Thank you Perry, that worked perfectly.
PS: This has been in development for a while now hasn't it. :)

…Only noticed your post now, still had the problem this morning, tried the script now, works perfectly
Thanks!
Would you happen to know if this problem is addressed in 2.0 ? If not, your script may be a good starting point for a built-in solution.

http://redmine.pfsense.org/issues/show/8 should cover all dead states problems.
I've add the script to the fit123 package (cass).

I had a similar problem to this but a little different. Wasted a half a day figuring out what the problem was but hey thats life…...
My setup is as follows: Pfsense 1.2.3-Release, Single WAN Static IP, I have pfsense running everything through a single interface using VLANs.
I have my asterisk box and the VOIP phones in their own VLAN/subnet with all the proper inbound and outbound NAT setup and with everything working properly.
Well on my LAN I foolishly opened my old asterisk test VM to see how I had some extensions configured and it attempts to register with my VOIP Provider. I realize what is happening and shutdown the VM. At this point I receive calls but no sound. I run a packet capture on both interfaces and see incoming RTP packets from the WAN and outgoing RTP packets from the Asterisk box on the VOIP VLAN.
All outgoing calls work fine. I check the asterisk box and it seems to still be registered with my VOIP Provider. Reboot the Asterisk box. Same problem. Clear all states in Pfsense. Same problem. Grr...I had been doing some work on the Asterisk box so I thought I found a bug or made a mistake. I simplify everything and make sure everything is working properly with Asterisk. Still didn't work.Reboot Pfsense. Everything works again......
So I guess the dead state problem is with any pfsense setup with more that two interfaces?
Will Perry's little hack help me too?

Hmmm, I just had this happen yesterday. My WAN IP changed, but for some reason the SIP registration entry didn't get punted. I deleted it manually and all was good. I looked at Perry's script, and while it looks fine, I sure think it would be nice if we could put scripts somewhere that they would be executed automatically when the filter is reloaded. I was looking at /etc/inc/filter.inc and saw that packages can put custom scripts in /usr/local/pkg/pf to do stuff like this - is there any reason we can't have a generic version of this? e.g. something like /usr/local/pf or some-such?

Ironically, the dyndns component does exactly what I need. e.g. it detects the WAN IP has changed, and sends an update request to my dyndns account to update the name of my gateway. I was looking where this gets called, and it is very specific to the dyndns code. When I was using clarkconnect as my gateway, there was a script (/etc/rc.local, if memory serves), that they would call when they detected that the WAN IP had changed. and you could hook whatever you wanted there. Maybe I am misreading the code now, but it looks like it doesn't make any attempt to detect this event, but just calls the interface configuration code. I would dearly love the same functionality in pfsense (and would be happy to take a shot at coding it up, if needed.)
-
There is a custom option to pfctl that we have, -b IIRC, that kills all states on a specified interface. This is new in 2.0, and supposed to be run whenever an IP changes, as well as after failover for a multi-WAN setup. There's a todo item open to test it. http://redmine.pfsense.org/issues/show/8 I suspect it has some outstanding issues.
States don't get deleted in 1.2.x when an IP changes or in any other scenario, so anything that stays active will retain the former NAT association.
-
Hmmm, that is interesting, since I am running 2.0 (a snapshot from 4/24, IIRC.) I will take a look at this and see if it is not working right all the time. Thanks!

(From a couple of posts back by someone else). I ignored this initially, because I don't have multiwan, but I suddenly realized I do have more than two interfaces! I have LAN and WAN as always, but my workaround for the havp issues was to install havp on my freebsd server and use re2 (wan is re0 and lan re1) to talk to that server on a dedicated subnet. So, in fact I have 3 interfaces live. I'm wondering if that is a big clue. I am at work now, but I will take a look at this later and post my findings…
-
Hmmm, I've tried unplugging the wan cable and plugging it back in 10 seconds or so later - I see warnings about the gateway being down, but it apparently didn't get a new IP - not sure how to force that to happen (I have a PPPoE WAN). I guess I can just wait a few days for it to change…

Depends on your ISP, but usually if you disconnect and reconnect PPPoE (reboot, or do so under Status>Interfaces) you'll usually get a new IP.
-
Okay, maybe I'll give the reboot a try. My concern with rebooting the gateway was that I thought it might do too much stuff, so it might not prove anything if it did get a new IP (and also, there would not be any states to kill). I think when I get home today, I will try to kill PPPoE and reconnect it as you suggested. Thx!
-
Oh, yeah what you're looking at is states, rebooting will wipe those. Disconnect/reconnect under Status > Interfaces
-
Cool, will do. Thanks again!

I ran out of time this morning, but I did get some useful information. Basically, the routine that gets called to flush states for downed gateways has a number of issues. I will try to complete my analysis today and follow up on redmine.
